Is there a wireless mouse that is split into right and left by a scroll wheel like PC's have?

We have a wireless mouse and keyboard. Neither are new. Purchased March of 2010. We have updated the hard drive to El Capitan. Now our mouse has a right and left click. We have a jumpy screen because we don't keep our hand on the mouse correctly. Is there a wireless mouse that will work with our computer that will help us keep our fingers in the right position.
